Image Transformation

{{container}}{{container layoutStyle="columns"}}(((

In most cases, you will transform XML messages to other XML messages, or you will transform JSON or EDI messages in another of these formats. However, sometimes you want to perform an image transformation. With this image transformation, you can convert images in specific formats to another format (i.e., png). This can come in handy when you want to standardize the image format before using it further downstream in your business application(s).

When turning to the Create phase of eMagiz, we need to open the flow and enter "Start Editing" mode to add the necessary component. For example, in the left panel, you can search for "Image." This will yield the following result.
